How do blood sinuses differ from veins?

Answer 1

Blood sinuses are blood spaces in tissue. Veins are blood vessels.

Blood sinuses, which are essentially simple spaces in tissue that are filled with blood, do not have epithelial walls according to histology. The best example of this is the sinusoids in the liver lobule. In contrast, veins are blood vessels that have layered walls; veins are the blood vessels that collect blood, and their innermost lining is made of thin endothelium.

Blood sinuses differ from veins in that they are wider and more irregular in shape, with thinner walls. They also lack a continuous layer of smooth muscle and are found in specific locations like the spleen, liver, and certain glands.
